RESUMO
Textual research is the first step, ensuring the safety and effectiveness of the clinical application, and also one of the main bases for determining the research scheme and experimental parameters in the development of famous classical formulas. It involves the origin and historical evolution of the prescription, the main function, the meaning of the prescription, the decoction method, as well as the original part, origin, dosage, processing method of the medicinal materials in the prescription. In view of these points, the author believes that the ancient and modern literature information should be comprehensively and accurately collected according to the standardized procedures and methods, combined with the historical continuation and cross-sectional analysis, in order to ensure the efficacy and safety of traditional Chinese medicine (TCM) famous classical formulas. The research and development plan of famous classical formulas was formulated from the perspectives of TCM theoretical characteristics, formula historical evolution, modern clinical value and practical feasibility. Under the premise of "compliance with the ancients", we should understand the common problems in the process of research and development, such as the origin, processing, dosage and decoction of TCM from the perspective of history and development, so as to widely gather the industry consensus and jointly explore the precious treasure of the famous classical formulas.
